The light requirements for growth and photosynthesis in seagrasses with emphasis on Texas estuaries : a literature survey [PDF]
, 1993 During the last 20 years, seagrass communities throughout the world have experienced decreased productivity and distribution. These declines have often been attributed to decreased water transparency as a result of turbidity or shading by epiphytic algae.

30% external quantum efficiency from surface textured, thin-film light-emitting diodes [PDF]
, 1993 There is a significant gap between the internal efficiency of light-emitting diodes (LEDs) and their external efficiency. The reason for this shortfall is the narrow escape cone for light in high refractive index semiconductors.

Quantization of the Superstring with Manifest U(5) Super-Poincare Invariance [PDF]
, 1999 The superstring is quantized in a manner which manifestly preserves a U(5) subgroup of the (Wick-rotated) ten-dimensional super-Poincar\'e invariance. This description of the superstring contains critical N=2 worldsheet superconformal invariance and is a

Dampak Sistem Penghawaan dan Pencahayaan terhadap Sick Building Syndrome
ComTech, 2013 Activities of office workers are most spent indoors. Unwittingly office buildings and enclosed spaces with air conditioning system usually do not have good ventilation and allow natural lighting. This condition may cause sick building syndrome (SBS). It

A Light Stop with Flavor in Natural SUSY
, 2012 The discovery of a SM-like Higgs boson near 125 GeV and the flavor texture of the Standard Model motivate the investigation of supersymmetric quiver-like BSM extensions. We study the properties of such a minimal class of models which deals naturally with

Probing Light Higgsinos in Natural SUSY from Monojet Signals at the LHC [PDF]
, 2014 We investigate a strategy to search for light, nearly degenerate higgsinos within the natural MSSM at the LHC. We demonstrate that the higgsino mass range $\mu$ in $100-150$ GeV, which is preferred by the naturalness, can be probed at $2\sigma ...

Energy conversion in Purple Bacteria Photosynthesis [PDF]
, 2011 The study of how photosynthetic organisms convert light offers insight not only into nature's evolutionary process, but may also give clues as to how best to design and manipulate artificial photosynthetic systems -- and also how far we can drive natural

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
